Patent DE-2342386-A1 (DE)
Title: Printing head position control - carrier deflecting rollers impart a meander trajectory to control band
Inventor: THURNER RICHARD
IPC: B41J7/64
Filed: 1973-08-22
Abstract: The design is applied to typewriters with a stationary platen and movable printing head of a spherical shape mounted on a carrier whose control bands have one of their ends attached to a positioning unit. The bands are guided parallel to the platen by deflecting rollers, while the rollers guide the band at the carrier end together with a shiftable roller. The latter is linked to a rocker by a tie and imparts the height setting movement to the printing head. A band is controlled at the carrier end by the rollers for imparting a turn to the printing head. The reduced number of rollers mounted on the carrier decreases the inertia effect as well as the effect of accumulated manufacturing tolerances upon the accuracy of positioning the printing head.
